SYSTEM SENSOR (P4RL) Horn Strobe, Wall, 4-Wire, Red, L-Series

The System Sensor P4RL horn strobe is a 4-wire, wall-mount L-Series notification appliance in red with FIRE marking. Because it is 4-wire, the horn and strobe connect to separate circuit inputs. As a result, panels can control audible and visual signals independently.

The horn is rated 88+ dBA at 16 volts. A rotary switch selects standard or 3.1 kHz tones, temporal or non-temporal patterns, and two volume levels. Meanwhile, the xenon strobe flashes at 1 Hz across the full operating voltage range, meeting ADA visible-signaling requirements.

System Sensor P4RL Horn Strobe Features

• Field-selectable candela settings: 15, 30, 75, 95, 110, 135, and 185 cd
• Automatic selection of 12- or 24-volt operation at 15 and 30 candela
• Plug-in design with universal mounting plate and wiring-continuity shorting spring
